Officials said the survey will help them understand women's need for and approach to family-planning services.

The 46-question survey was sent out in September and October. Participants were asked how many men they had sex with over the last year, whether a man ever poked holes in a condom to get them pregnant and how they felt emotionally the last time they had unprotected sex.

The state said the names of those who return the survey will be kept private.
